FH8500Benefiting from their know-how

and leading position in liquidmetering, FAURE HERMAN have

developed the ultrasonic flowmeter you need for custody

transfer applications of liquidhydrocarbons. The FH8500 is

suitable for the measurement ofcrude and refined products.FH8500 features bring key technical advantages and

excellent ROI for end-users.

The pressure drop reduction (filter+flow

conditioner+meter) comparedwith turbine and PD meters

minimizes the power consumption of the

metering point.

The filter removal reducesthe maintenance cost of the

metering point.

An Indisputable Concept Innovation

Ultrasonic Transit Time MethodThe FH8500 theory of operation is based on theUltrasonic Transit Time Method. This method gives access to the difference in propagationtime between ultrasonic pulsestransmitted along and againstthe flow from A to B andB to A, TAB and TBA respectively. The average flow velocity VAB along AB is proportional to ( TBA - TAB ).

The flow velocityProfile CompensationThe average speed measuredalong the ultrasonic propagationpath depends on the flow velocity profile.The FAURE HERMAN ultrasonic technology providesdetailed information on the flowvelocity profile. An accuratemeasurement of the flowratecan be achieved by rebuildingthe whole flow velocity profileacross the pipe.

The FH8500 multi-path ultrasonic flowmeter is the only flowmeter that integrates 36 transducers generating 18 ultrasonic beams, providing a 3D view of the flow velocity profile.

Thanks to a powerful integrated processing unit, using the leading-edgedigital technology, the FH8500 providesan integrated and compact meteringsolution to our customers. A high speed processor measures transit time with a very high resolution on the 18 ultrasonic paths.

Swirls and Asymmetric Profiles Compensation

Thanks to the unique FH8500tri-dimensional symmetric pathsconfiguration, the flowmetermeasurement accuracy is keptwithin the international standards requirements whenswirls and asymmetric profilesare present in the pipe.

Swirls and asymmetric profiles are compensated byusing FAURE HERMAN uniquesoftware.

Thanks to the FH8500 ultrasonic path configuration,the measurement accuracy isstill in compliance with APIrecommendations for custodytransfer applications after loosing one transducer, representing 3 ultrasonic paths.

This unique FH8500 configuration offers the advantage of maintaining custody transfer accuracy with only 15 ultrasonic pathsallowing for scheduled system maintenance.

FHview Communication SoftwareFH8500

I/O settingThis screen gives access to the configurationof the analogue 4-20 mA inputs and outputs.Users can allocate one parameter, such as flowrate or VOS (Velocity of Sound), to eachof them and adjust the operating range.

Global parameters displayThis screen provides instantaneous informationon the FH8500 flow conditions such as grossflowrate, average VOS, etc. In addition, usersget data relating to the operating status ofmeter, number of working beams, alarms, and average ultrasonic signal level.

Graph visualisationA range of functionalities are available to trackand view average VOF, VOS and signal gainover the time.

Measurement integrityThis screen gives all necessary parameters

relating to the 18 ultrasonic paths, VOF (Velocity of Flow), VOS and signal gain.These data allow to check the measurement

integrity on each single beam.

Data and events loggersUsers can download and record data from the

flowmeter with respect to the previously defined period of time. These data relate to the

flowmeter parameters. Dated events such as alarms can be downloaded and recorded.

The FHview SoftwareFhview is the PC software for

the configuration and operationof the FAURE HERMAN FH8000

ultrasonic product line. The FH8000 product

line includes ultrasonic flowmeters for both fiscal and

process applications. The communication between

Fhview and the FH8000 is usingMODBUS protocol via a

Remote Control and Local Display

Local displayThe local display provides non-fiscal information about the flowconditions, flowrate, totalizer,VOS, etc. The display units canbe modified by using either theconfiguration software or theinfrared remote control.

Flow velocitiesThe maximum and extended flowrates have been determined,based on a flow velocity of 10 m/s and 15 m/s respectively.

Global parameters displayThe intrinsically safe infrared remote control, unique to FAURE HERMAN, constitutes an additional originality. This hand held unitallows for non-contact communication and adjustment of displayparameters and restricted access to various configuration levels, and alarms management.
